Cassandra was abandoned as an infant but rescued and later adopted by Angie Baxter Hubbard and Jacob Foster. When Angie and Jacob divorced, Cassandra moved to Paris to live with her father. When Cassandra was eighteen, she arrived in Pine Valley to visit her mother and to meet her mother's presumed-deceased husband Jesse. Cassandra did not care for Jesse or her mother's plans to remarry but she changed her mind after she witnessed how much Jesse loved Angie.

While Cassandra was in town, she befriended Colby Chandler and Andre "Dre" Woods. They were together in a car one night and accidently ran into something on a dark road. The next day, they suspected they had killed a man named Richie Novak. The teens lied to cover up the events of the night but eventually the truth came out. Richie had been killed by someone else before the teens had hit him. Shortly after Cassandra and her friends were cleared, she returned to Paris to be with her father.
